    齿轮马达
    齿轮马达在结构上为了适应正反转要求,进出油口相等、具有对称性、有单外泄油口,将轴承部分的泄漏油引出壳体外;为了减少启动摩擦力矩,采用滚动轴承;为了减少转矩脉动,齿轮液压马达的齿数比泵的齿数要多。
    齿轮液压马达由干密封性差、容积效率较低、输入油压力不能过高、不能产生较大转矩。并且瞬间转速和转矩随着啮合点的位置变化而变化,因此齿轮液压马达仅适合于高速小转矩的场合。一般用于工程机械、农业机械以及对转矩均匀性要求不高的机械设备上。
    轴向柱塞泵除阀式配流外,其它形式原则上都可以作为液压马达用,即轴向柱塞泵和轴向柱塞马达是可逆的。轴向柱塞马达的工作原理为,配油盘和斜盘固定不动,马达轴与缸体相连接一起旋转。当压力油经配油盘的窗口进入缸体的柱塞孔时,柱塞在压力油作用下外伸,紧贴斜盘,斜盘对柱塞产生一个法向反力p,此力可分解为轴向分力及和垂直分力Q。Q与柱塞上液压力相平衡,而Q则使柱塞对缸体中心产生一个转矩,带动马达轴逆时针方向旋转。轴向柱塞马达产生的瞬时总转矩是脉动的。若改变马达压力油输入方向,则马达轴按顺时针方向旋转。斜盘倾角a的改变、即排量的变化,不仅影响马达的转矩,而且影响它的转速和转向。斜盘倾角越大,产生转矩越大,转速越低。

    液压马达
    液压马达按其结构类型来分,可以分为齿轮式、叶片式、柱塞式和其它型式。按液压马达的额定转速分为高速和低速两大类。额定转速**500r/min的属于高速液压马达,额定转速低于500r/min的属于低速液压马达。高速液压马达的基本型式有齿轮式、螺杆式、叶片式和轴向柱塞式等。它们的主要特点是转速较高、转动惯量小、便于启动和制动、调节(调速及换向)灵敏度高。通常高速液压马达输出转矩不大所以又称为高速小转矩液压马达。低速液压马达的基本型式是径向柱塞式,此外在轴向柱塞式、叶片式和齿轮式中也有低速的结构型式,低速液压马达的主要特点是排量大、体积大转速低(有时可达每分钟几转甚至零点几转)、因此可直接与工作机构连接;不需要减速装置,使传动机构大为简化,通常低速液压马达输出转矩较大,所以又称为低速大转矩液压马达。

    液压马达
    工作原理,当压力油经固定的配油轴4的窗口进入缸体内柱塞的底部时,柱塞向外伸出,紧紧**住定子的内壁,由于定子与缸体存在一偏心距。在柱塞与定子接触处,定子对柱塞的反作用力为 。力可分解为和 两个分力。当作用在柱塞底部的油液压力为p,柱塞直径为d,力和之间的夹角为X时,力对缸体产生一转矩,使缸体旋转。缸体再通过端面连接的传动轴向外输出转矩和转速。以析的一个柱塞产生转矩的情况,由于在压油区作用有好几个柱塞,在这些柱塞上所产生的转矩都使缸体旋转,并输出转矩。径向柱塞液压马达多用于低速大转矩的情况下。CALZONI卡桑尼 MR300D-N1T1N1N1N0401
